--- Comment #6 from wbrana at gmail.com ---
It is possible it was caused by some Gentoo bug 
like https://bugs.gentoo.org/show_bug.cgi?id=614844

with sys-devel/clang-4.0.0-r2

time clang main.clang.ii -std=c++11 -c -w
real    0m6.071s
user    0m5.984s
sys     0m0.081s

time clang main.clang.ii -std=c++11 -c -w -O2
real    0m13.222s
user    0m13.134s
